WWNESSES ATTORNEY MARCUS BERKOWITZ, or SPRING VALLEY, NEW YORK.

COMBINATION-STOVE.

Application filed April 30, 1918.

To all whom it may concern: 1

Be it known that I, MARoUs BERKowrrz, a citizen of the United States, residing at Spring Valley, in the county of Rockland and State of New York, have invented certain new and useful Improvements in Combination-Stoves, of which the following is a specification.

My invention relates to new and useful improvements in a cooking stove, and an important object of the same is to provide a device wherein the grate may be shaken, the movement of which operatesan ash sifter immediately below the grate. The arrange ment of these parts is such, that the ash sifting means is arranged wholly within the casing of the stove.

Another object of my invention is to construct the sifting means in such a manner that the bottom thereof may be swung downwardly to permit the cinders remaining in the sifting means to be deposited in a removable container.

Another object of my invention is to cast the various parts of the stove proper in such a manner to facilitate the eflicient operation of the various parts thereof.

Other objects and advantages of the invention will become apparent during the course of the following description.

In the accompanying drawings forming a part of the description and wherein like numerals are employed to designate like parts throughout the same,

Figure 1 is a sectional front view of the stove, with parts thereof broken away to show the construction of the various parts.

Fig. 2 is a transverse vertical sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a perspective view of the grate and the sifter showing the details thereof.

In the accompanying drawings, wherein is shown the preferred embodiment of my invention, the numeral 1 designates the body portion of the stove having the oven 2 therein, the wall 3 of which forms one side of the fire-box 4. As usual, the upper part of the fire-box communicates with a heating chamber which is arranged between the top of the oven 2 and the top of the stove 6.

The walls of the fire-box 4 are provided with the lining bricks 7. A grate 8 is movably mounted in the bottom of the fire-box 4 adjacent the lower end of the lining bricks 7, and is shown in the present instance as a rectangular frame 8 having stationary grate Specification of Letters Patent.

bars 9. As more clearly shown in Fig. 3 of the drawings, the transverse ends of the rectangular frame are provided with longitudinally extending pintles 10, one of which is round in cross section, and the other being square as at 11 at intervals throughout its length. The intermediate portion 12 of the square pintle is round in cross section so that 1t may be journaled in the front 13 of the fire-box. The other pintle 10 is journaled in a recess in the back 14 of the fire-box. It will therefore be seen that the grate as a whole, may be rocked or dumped as the case may be, by means of a handle 15, shown in the present form as a wheel 16 having a square opening at its center for the reception of the outer squaredend 11 of the pintle 10. It will be further noted that the outer squared end 11 of the pintle projects a substantial distance beyond the front 13 of the fire-box. A gear segment 17 having a squared opening 18 therein is positioned upon the inner squared portion of the pintle 10 so that the segment depends from the grate bar and the teeth thereon are arranged below the horizontal plane of the grate.

The front and rear walls of the fire-box are provided each with an inwardly eX- tending horizontal flange 19, both of which are arranged in the same horizontal plane a substantial distance below the grate 8. These flanges form guides and supporting means for the sifter 20 having outwardly extending horizontal flanges 21 arranged upon its transverse ends. These flanges 21 are adapted to engage with the guides or flanges 19 for suspending the sifter in the casing below the grate 8. One of the flanges 21 is provided with a plurality of alined spaced openings 22 for the reception of the teeth on the gear segment 17. In this connection it is to be understood that I may employ one or more gear segments 17 to engage with a similar number of rows of openings 22. It is also to be understood that the gear segments 17 may be associated with any form of grate or grate bars for cooperation with the sifting means. The sifter 20 comprises a rectangular frame having an open top and bottom, the bottom of which consists of a screening element 23 which is hingedly connected' to the bottom of the sieve by means of the hinges 24. These hinges pivotally connect the screening element with the 1011- gitudinal ends of the sieve, and the opposite longitudinal edge of the screening element .box.

is normally retained in contact with the sieve 20 by means of a latch 25. This latch consists of an elongated vertical plate which is pivotally connected to the longitudinal side of the rectangular frame of the sieve, and this plate is provided upon its inner face a substantial distance from the free end thereof, with an extension 26 which is arranged at right angles to the elongated plate.

The longitudinal side Wall 27, of the fire-box extends downwardly to the point in close proximity to the lower end or bottom of the sieve. I

An ash receiving chamber 28 is located immediately below the sieve 20, and is formed by extending the walls of the fire An ash receiving container 29, in the form of a sliding drawer, is arranged in the ash receiving chamber so as to receive the ashes and cinders which are dropped from the sieve 20.

The operationof the sifting mechanism is as follows Assuming that there is a fire in the firebox at of the stove, and it is desired to shake the ashes therefrom, the handle 15 is inserted upon the square end 11 of the forward pintle 10. The pintle is then actuated to rock the grate 8 and the rack segment 17. Sincethe teeth of this segment mesh with the openings 22 in the flange 21 of the sifter, the movement of the segment will cause the sifter to slide back and forth upon the guides or supporting flanges 19. The movement of the grate will cause the lower ashes and cinders to drop between the grate bars 9 onto the screening element 23 of the sifter. The movement of this sifter will agitate the ashes deposited upon the screening element and cause the fine ashes to sift through the screening element and thence into the ash receiving receptacle 29. It is understood that the cinders which may be used as fuel are retained in the sifter. The container 29 is then removed from the casing of the stove and the ashes therein are dumped into a proper receptacle. The receptacle 29 is then replaced in the casing in such a man nor that it is possible to gain access to the latch 25. This latch is gripped below the angular extension 26 and is moved outwardly from the sifter so that the screening element 28 swings downwardly by the weight of the cinders thereon. As soon as all of the cinders have been deposited in the receptacle 29, the screening element 23 is then placed in its proper position by the latch 25,

vand the receptacle 29 is removed so as to deposit the cinders in their proper place.

It is therefore evident that the invention performs two useful functions at the same time, in shaking the grate and sifting the ashes which fall therefrom.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts may be re sorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having described my invention, I claim 1. In combination with a grate, an ash sifter, said Sifter being provided with a plurality of alined space openings, and a gear segment secured to said grate and operating in said openings.

2. In combination with a grate, of an ash sifter, said sifter being provided with flanges upon opposite ends, one of which is provided with a plurality of alined spaced openings, a gear segment secured to said grate and having operative connection with said openings, and means for rocking said grate.

3. An ash sifting mechanism comprising a fire box, a grate rotatably mounted there in, a gear segment secured to the grate and depending therefrom, a pair of supporting guides arranged below the grate, an ash sifter slidably supported upon said guides, said sifter having a pair of outwardly extending flanges for engagement with said guides, and one of said flanges being provided with a plurality of alined spaced openings for engagement with the teeth of the gear segment whereby rocking movement of the grate will transmit reciprocatory movement to the ash sifter. I

In testimony whereof I afiix my signature in presence of two witnesses.
